Beijing, October 21 (Youth.cn) - On October 20, in Suzhou, for days, a persistent cold air has brought a deeper sense of autumn for the Master-of-Nets Garden. The ancient trees, including purple-leaf plums and magnolias, are now adorned with a brilliant tapestry of colors. Together with the classical pavilions and tranquil ponds, they form a scene of picturesque beauty. Photo/CFP
